Alternative Method for Initialization
APPENDIX C
The PCnet-PCI controller may be initialized by perform-
ing I/O writes only. That is, data can be written directly to
the appropriate control and status registers (CSR in-
stead of reading from the initialization Block in memory).
The registers that must be written are shown in the table
below. These register writes are followed by writing the
START bit in CSR0.
